GT all whom it may concern: Be' it known that I, Lno JNo. BAYER, a citizen of the United States, residing at St.

Louis, State of Missouri, have invented cer- Sj tain new and useful improvements in Boileri Cleaners, oi which the following is a full,

elear, and exact.description, reference being had to the accoi'upanying drawings, forming fspart hereof.

ents ill'lmlltl' cleaners; and it consists in yth'e novel detailsof construction more fully forth in the specification and pointed out 55in the claims.

;f.-' In the drawings l igure 1 is a side elevalt i0n of one form of-hoiler showing my ini 1 vention applied thereto; Fig.2 is a horizontal section on the zig-zag line 92 of ig.--1; Fig. 3 i s'-'a vertical transverse section the-jl-ine 33'of- Fig. 1; Fig. 1 is a detail 69 j-planpf the plate (partly broken) closing the opening in the wall of as lfurnace t-hrough'whichthe spray-nozzlcs play; Fig. 'f'5*'is;a-'side elevation of a modified boiler 5"showing a modified form of my invention applied thereto; Fig; Sis a 'vertical transverse sectionon the-line -6-6'of Fig. 5-; Fig.

is an enlarged elevational' detail'ot' the header with spray-nozzles attached directly thereto; Fig. 8 is a .horizpntal section of the spi-ayhead'on the line 8'S of Fig. 9; Fig. 9 is a. vertical section on the line 9 9 of Fig.

*9 of the teifininal'spray-head or" the series; and-Fig. 11 is an end view of Fig. 10.

The object of my invention is to direct sprays; jets,-or sheets of steam (or' equiva- "-lent fluid) into and through the spaces between the tubes of a water-tube boiler for purposes of cleaning the tubes of any accumulations of soot. dirt, ashes and the like,

'7 suitable provision being made to sweep the entire area ofythe tubes by such" cleaning agent with a view of removin lations throughout the full boiler.

. A further object is to direct the cleaning agent or portions of it in the general direction of the draft, so that the draft may be materially assisted during the cleaning operation; a further object is to provide means for cleaning any section of the boiler inde- 'pendentlyjof the remaining sections. and in fineto provide further and other details the ength of the advantages of which will be clearly appan My invention has relation to improve-' 8-; Fig. 10 is a section corresponding to Fig.-

REISSUED ent-from a detailed description: of the inyention, which is as follows:'- i i -,Referring to the drawin and for the present to Figs. 1 to 4, inc usive. F re resents the furnace; (the walls being broken away in parts) of awell known "typ of water-tube boiler (Babcock"& .Wilcox S representing the shell of the boiler and-T, the water tubes. As well understood inthe' art thewate'r-t'ube port-ion is divided off into independent sections by battle-plates a,' the general draft being rearward and upward .from the firebox F". Dis osed along one of the side walls of the urnace'opposite each section or I division -'.ebetween*"and on 7 either side of, the bathe-plates are; vertical openings 0, taperinginwardly'and closed by plates P set in the brick-work, through elongated slots 8 of which plates, the steam spray-nozzles are inserted to project jetsof steam into, through and across the spaces between the water-tubes for removing any dirt, ashes or other foreign material which accumulates thereon from time to time; In the present case, I provides; steam supply or'coiulucting pipe 1 leading from the steamspace of the shell," bringing the-pipe down l'ilougside the bottom of'the furnace wall as shown; 'Along this portion' of the steam pi are disposed tees 2 to which (and to th: pipe) are connected branches 3;; provided with valves 4 of any conventionaltype, and terminating in hollow swivel joints 5 of any well known construction tube-found on the, market, fIOlliWhlCh joints lead headers 6 1181 9 shown. The headers as well as thebranch'es' are disposed at-1'ight an les toathe 'inclinedwater-tubes, each hea er'being provided with a handle or lever L by which axial rotation may be imparted to such header. Leading from each header'areshunts or ofl sets 7 disposed parallel tothe wall of the furnace; for a central position "of the' parts as presently will more fully appear), the shunts progressively diminishing in length from bottom upward, whereby their outer endsare disposed in a common vertical line corresponding substantially to the central vertical axis of, each opening D; From the shunts 7 lead nozzles 8 terminating in than 105 ing spray-heads 9, the latter being provided w th passages m diverging from the. passage-way o the nozzle and disposed in the general plane of oscillation of the nozzle, a

second downward-1ytrcnt' ug passage-way ing the steam across the space between the water-tubes. The upper ends ofthe headers 'i'tnot1-for -th I 7'refe1'redto 1 p y rning on' thesteam, seizing the hanrection of such draft. Each section of the :thewater-tube portion T of the boiler is set of steam as near parallel to the planes of the :straps 10 spanning the openings 0 and seofi'sets 7, the. bases .of the nozzlesare brought canjsweep across the full width of the re- .duced endi-of such opening. Otherwise,- l sinc'trthe' header 6 is inclined to such vertation couldfbe arted to the header were without theuse of shunts as the'inclination of the tubes is insufficient to either interfere the exposed portion of the tube (instead of f air Huu'vintuat the Hope! time. the top m being formed in the bottom head 9, 0pposite the middle section, and an upwardly trending passage-way m in the top head- 9' of .the terminal section of the boiler, to direct 'a steam jet in the general. direction .of the line of'draft, the passages m projectare supported and have suitable hearings in cured to the furnace wall. By means of the in theplane-ofthe vertical axis of the open- ;ing 0, and hence, when rotation is imparted to any. header,'the free ends of the nozzles tial axisof the opening'O, the nozzles would -fi ,.trike the sides of the opening, and no rom ually diminishing ofisets.

Provision may however, be ma e to clean all the sections simultaneously by simply connecting the several handles L by a common link 11- (loosely coupled to all the handles) as shown in the modification in Fig. 5. In this modification at a less incline from that of the first form described, and for practical purposes the headers'fi maybe. mounted vertically, and

the nozzles 8. be coupled directly thereto with the free oscillation of' the nozzles, or prevent the steam jets from shooting across the spaces between the tubes. Of course, the object sought is to project the sheets or jets spaces between the tubes as possible, to insure thatthe steam reaches every rtion of cutting across the tube), but in the modifica-- tion alluded to (Fig. 5), this result is practically attained though :perhaps not as erfectly as in the first type described, w ere the planes of oscillation of the nozzles are parallel to the planes of disposition of the water-tubes. To prevent theformation of a vacuum in the headers, and allow free influx of each header is pror a with a vent-valve o of any conventional type, the valve seating during the blowing operation, and unseating at the conclusion thereof to allow for free influx ofair into the pipes to fill any vacuum tending to form therein, as a 'result of condensa-tio'nof the steam.

-The central position of the parts corresponds to-that where the nozzles are on the center vertical line of an opening 0 and from which line they are free to oscillate in either direction to cause the steam jets to sweep the entire area of a given section as defined by the bathe-plates a.

Owing to the presence of the battle-plates in Fig. 1, will be first up in front of the first plate, then down between the plates, and nally u again beyond the last plate. So that the ottom spray, head opposite the center section between the bafiles (Fig. 3) must be mounted so as to 'rect the passages m downward instead of' pward, that is to say,

they inust be the reverse to the top sprayhead opposite the terminal section (Fig. 6). Having described my invention, what I 1, in combination with'a boiler havingseries of water-tubes disposed in superposed parallel planes, :1. series of transversely glisposed battle-plates intersecting the tubes and dividing the boiler into independent sections,

nozzles located opposite each section for projecting a. cleaning fluid into and throu h the spaces between the tubes, and means fir moving the discharge ends of the nozzlesin planes parallel to the general planes of disposition ofthe tubes. f

'In combination with a boiler having series of water-tubes disposed in superposed parallel pllanes, a 'seriesof transversely dis-- osed ha e-plates intersecting the tubes and ividing the boiler into independent sections, nozzles located opposite each section for projecting a cleaning fluid into, through and across the spaces between the tubes, and means for moving the clischargeends of the nozzles in planes parallel to the general planes of disposition of the tubes.

3. In combination with a boiler having series of wate'ntubes disposed in superposed inclined planes, a furnace inclosing'said tubes, the wall of the furnacebeing rovided with-vertical side openings, a fiui -supply pipe disposed onthe outside of the furnace wall, an axially rotatable header opposite an openingin the wall disposed substantiallyat right'an'gles to the planes of disposition of'the-water-tubes'a series .of ofi'sets lea ing from the header, and nozzles extending from-said offsets into the boiler furnace and projecting the fluid into and through the spaces between the tube; durifl!" th rotation of the headers. the Several ofliscls being appardoned in length to br ng the basis of th llt nozzles in line with the center of the o ening in the furnace wall, said center eorrespending to the center of the arc of oscillation of the nozzles.

4. In combination with a Water-tube boiler, a fluid-ejecting and cleaning nozzle positioned on the side'of the tubes and pro- 'vided with-passages projecting the cleaning fluid between the tubes and across the space between the tubes and an independent passage for directing the fluid in the general direction of the line of draft.

5. In combination with a boiler having a section carried by said pipe, a series of nozzles leading from each header toward the boiler and projecting the steam into and across the spaces between the tubes, a lever jarm projecting in the opposite direction from each header, and a link pivotally coupled to the several lever arms whereby the several headers may berotated in unison and the several sections of the boiler cleaned simn' taneously.

6. In combination with a boiler having a series of inclined water-tubes disposed in snperposed parallel planes, a series of transversely dis osed batlle-plates intersecting the tubes and dividingtheboiler into independent sect-ions, a steam-snpnly "pipe, a header rotatably coupled to said plpe opposite e2 1 boiler section and'disposed substantially atri ht angles to the Water-tubes, a series of 0 sets or shunts of progressively diminish- ,ing length leading from each header, and

nozzlesextending from said offsets toward the Water-tubes for projecting jets of steam into, and through the spaces between the tubes during the rotation of the headers, the bases of the nozzles being disposed along a substantially vertical line.

In testimony whereof I aflix my signature, in presence of two witnesses.
